Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this study is to assess the clinical, biomechanical and functional outcome 2 years after anterior cruciate ligament (ACL) repair and InternalBraceTM augmentation now in direct comparison to ACL reconstruction and to identify potential deficits compared to the contralateral healthy side as well as with a knee-healthy age-matched collective. In addition, socio-economic aspects such as return to work and sports and treatment cost will be compared between both techniques.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Injury of the anterior cruciate ligament (ACL) is one of the most common injuries of the knee. Since May 2016, patients with proximal ruptures of the ACL have been treated with direct repair and InternalBraceTM Ligament Augmentation at the University Hospital of Basel.

The remodelling of hamstring grafts used for ACL reconstruction is completed at the earliest 2 years after the surgery. The aim of this study is to assess the clinical, biomechanical and functional outcome 2 years after anterior cruciate ligament (ACL) repair and InternalBraceTM augmentation now in direct comparison to ACL reconstruction and to identify potential deficits compared to the contralateral healthy side as well as with a knee-healthy age-matched collective. In addition, socio-economic aspects such as return to work and sports and treatment cost will be compared between both techniques.
